A novel integrated approach to heat transfer enhancement using baffles and inner fins in helical coil heat exchangers
Full text linkThe global rise in energy demand has intensified the need for improved efficiency in thermal systems, particularly in industrial and high-load applications. Heat exchangers play a critical role in energy recovery, and enhancing their performance is essential for maximizing overall system efficiency. This study presents a numerical investigation of a shell-and-helical coil heat exchanger enhanced by the integration of shell-side baffles and tube-side internal fins. A three-dimensional model was developed to simulate turbulent flow and heat transfer across four structural configurations: a conventional design, a baffled configuration, an internally finned tube design, and a combined baffle–finned configuration. The simulation results indicate that the integrated configuration achieves the highest performance improvement, with up to a 33 percent increase in effectiveness compared to the conventional design, reaching a maximum effectiveness of 0.60. The same configuration also demonstrated a peak thermal-hydraulic performance value of approximately 1.60 at low flow rates, reflecting an effective balance between heat transfer enhancement and pressure loss. The numerical model was benchmarked against experimental data with a maximum deviation of about 2 percent, supporting its reliability. The study introduces a novel enhancement strategy that combines two geometric improvements into a single configuration, offering a compact and efficient solution for advanced thermal system applications

Dual-Band, Dual-Mode, Circularly Polarized Fully Woven Textile Antenna for Simultaneous Wireless Information and Power Transfer in Wearable Applications
No full textEl trabajo describe una antena dual-band dual-mode para transmisión inalámbrica simultánea de energía e información, con polarización circular y completamente integrada en textil. Los modos de transferencia de energía e información operan a 2.4 y 5.4 GHz, respectivamente. El elemento radiante está basado en un parche rectangular con un slot con forma de U asimétrica. El rectificador se conecta a la antena a través de un puerto con estructura T-match, que proporciona simultáneamente adaptación compleja conjugada y polarización circular. Por otro lado, para la conexión de la señal de información se utiliza un puerto coaxial convencional. Se fabricado y caracterizado un prototipo, obteniendo valores de potencia rectificada y eficiencia de conversión comparables al estado del arte relativo a antenas implementadas en tecnologías convencionales, demostrando así la viabilidad de la alternativa propuesta.Agencia Estatal de Investigación (AEI), con los proyectos PID2021-126301NA-I00 y EQC2019-005768-P.

RETORCH*: A Cost and Resource aware Model for E2E Testing in the Cloud
Full text linkMoving testing to the Cloud overcomes time/resource constraints by leveraging an unlimited and elastic infrastructure, especially for testing levels like End-to-End (E2E) that require a high number of resources and/or
execution time. However, it introduces new challenges to those already faced on-premises, like selecting the most
suitable Cloud infrastructure and billing scheme. We propose the RETORCH* test execution model that estimates
and compares the monetary cost of executing an E2E test suite with different Cloud alternatives, billing schemes,
and test configurations. RETORCH* goes beyond the mere cost billed, and selects the solution that best aligns
with the test team strategy using the data of on-premises prior executions and the tester’s experience. This cost is
broken down into the cost incurred to execute the test suite (testing cost) and possible unused infrastructure
(overprovisioning cost). Based on these distinct costs, the test team can compare different Cloud and test configurations. RETORCH* has been evaluated using a real-world application’s E2E test suite. We analyze how the
different decisions taken when the suite is migrated to the Cloud impact the cost, highlighting how RETORCH*
can help the tester during Cloud and test configuration to make a more informed decision.This work was supported in part by the project PID2019-105455GB-C32 under Grant MCIN/AEI/10.13039/501100011033 (Spain), in part by the project PID2022-137646OB-C32 under Grant MCIN/AEI/10.13039/501100011033/FEDER, UE, and in part by the project MASE RDS-PTR_22_24_P2.1 Cybersecurity (Italy)
La Radioterapia Intraoperatoria como Estrategia Oncológica: Un Análisis de su Potencial Terapéutico y Futuro Clínico
No full textLa radioterapia intraoperatoria (RIO) es una técnica que combina cirugía y radioterapia en una misma intervención, permitiendo administrar dosis de radiación directamente en el área tumoral durante la cirugía. Esta estrategia ofrece ventajas clave, como la posibilidad de irradiar con mayor precisión los tumores, reduciendo el daño a los tejidos sanos circundantes y mejorando los resultados oncológicos. Actualmente, se utiliza en el tratamiento de varios tipos de cáncer, como el de mama, recto y páncreas, especialmente en casos donde el tumor es difícil de erradicar completamente con cirugía convencional. En el futuro, la RIO promete avances significativos con el uso de tecnologías más precisas, como la radioterapia de intensidad modulada y la integración de imágenes intraoperatorias, lo que podría mejorar aún más la eficacia terapéutica, reducir las recurrencias tumorales y optimizar la calidad de vida de los pacientes
